SLCC Physiology Exam 1 UPDATED
ACTUAL Questions and CORRECT
Answers
Anatomy - CORRECT ANSWER - Study of the structure of the body
Physiology - CORRECT ANSWER - Study of the function of the body-function depends
of structure
Level of Organization - CORRECT ANSWER - Cell, Tissue, Organ, Organ System-each
cell classified by function
4 Cell Types - CORRECT ANSWER - Epithelial Cells, Nervous Cells, Muscle Fiber Cells,
Connective Tissue Cells.
4 Tissue Types - CORRECT ANSWER - Epithelial Tissue: inside and out is protected by a
continuous layer-absorption secretion-exocrine ducts-endocrine internal , Nervous Tissue:
communication through electrical impulse, Muscle Fiber Tissue: Movement, Connective Tissue:
connect/link, anchor/support body structures
Elastic Fibers - CORRECT ANSWER - yellow fibers ; made of protein elastin ; stretchy ;
add flexibility to certain connective tissues
Collagen Fibers - CORRECT ANSWER - Fiber that Bind bones and other tissues to each
other; Found in tendon, ligaments, skin, etc
Fibroblasts - CORRECT ANSWER - Are cells that secrete matrix proteins
Ground Substance - CORRECT ANSWER - Is the matrix of loose connective tissue
,Endocrine System - CORRECT ANSWER - Hypothalamus, pituitary gland, adrenal gland,
thyroid gland, parathyroid gland, thymus, pancreas
Provide communication between cells of the body through the release of hormones in the
bloodstream
Nervous System - CORRECT ANSWER - Brain, Spinal Cord, Peripheral Nerves
Provide communication between cells through electrical in pluses and the release of
neurotransmitters in between small gaps in certain cells
Musculoskeletal System - CORRECT ANSWER - Skeletal Muscles, bones, tendons and
ligaments
Support the body; allow voluntary movement of the body and facial expression.
Cardiovascular System - CORRECT ANSWER - Heart, Blood vessels, blood
Transport molecules throughout the body in the bloodstream
Respiratory System - CORRECT ANSWER - Lungs, pharynx, Trachea, Bronchi
Bring oxygen into the body and expel carbon dioxide from the body
Urinary System - CORRECT ANSWER - Kidneys, ureters, Urinary bladder, urethra
Filters blood to regulate the acidity, blood volume, and ion concentration; eliminates wastes
Gastrointestinal System - CORRECT ANSWER - Mouth, esophagus, stomach, small
intestines, large intestine, liver, pancreas, gall bladder
Break down food and absorb it into the body-lumens are external
Reproductive System - CORRECT ANSWER - Gonads, reproductive tracts and glands
Generate offspring
, Immune System - CORRECT ANSWER - White blood cells, Thymus, Lymph Nodes,
Spleen, tonsils, adenoids
Defend the body agains pathogens and abnormal cells
Integumentary System - CORRECT ANSWER - Skin
Protects the body from the external enviroment
Membrane Potential - CORRECT ANSWER - the difference in electrical potential or
voltage across the cell membrane
TBW - CORRECT ANSWER - By percent, 60/40/20 rule: 60% of the body is water: 40%
of this is in the Intracellular Fluid (ICF), and 20% is in the Extracellular Fluid (ECF).
ICF - CORRECT ANSWER - Fluid within cells. About 70% of total body water or 40% of
the adults body weight
ECF - CORRECT ANSWER - Between the cells of tissues: interstitial fluid, plasma in
blood vessels, and lymph in lymphatic vessels
ICF vs. ISF - CORRECT ANSWER - Separated by cell membrane to retain gradients and
cell potential
ISF vs. Plasma - CORRECT ANSWER - Epithelial cells separates these two parts of the
ECF to keep proteins inside the bloodstream.
Homeostasis - CORRECT ANSWER - the maintenance of a constant internal environment
by an organism. Example: temperature, blood pressure, Blood pH
Homeostasis Regulation - CORRECT ANSWER - The adjusting of physiological systems
within the body through feedback mechanisms
